Description
Technical field:
The utility model relates to a kind of vulcanizing press, specifically a kind of vulcanizing press hot plate temperature control device.
Background technology:
It is the way of always advancing quantity of steam of regulating hot plate that the control of vulcanizing press hot plate temperature is adopted, and promptly compares with curing temperature according to detected hot plate temperature and regulates the into size of quantity of steam.It is subjected to the influence of boiler supplying steam pressure, when the boiler supplying steam pressure is high, the pressure that hot plate advances steam is just big, its programming rate will be accelerated, the temperature lack of uniformity strengthens, reason is just fast from advancing nearly that section programming rate of steam port, and steam port that section programming rate far away is just slow from advancing, and has caused the temperature of hot plate unbalanced like this.What it was regulated is that whole hot plate always advances quantity of steam, when wherein a certain section measurement temperature is higher than setting value, it can't realize closing separately the steam valve that advances on this road, and can only be turning down and always advance steam valve slowly, reduce into quantity of steam, it be with hot plate mean temperature (hot plate each point temperature sum, again divided by count mean temperature) for reference value, control is the quantity of steam that advances of whole hot plate, and it is just big that the temperature value of hot plate each point differs.Simultaneously, its row's condensed water method also is to concentrate discharging, whole hot plate is by row's condensation water valve and a drain valve discharging condensed water, when a certain section measurement temperature wherein very low (with setting value time), it can't realize opening separately row's condensation water valve discharging condensed water on this road, and can only open total row's condensation water valve discharging condensed water.Because it is balanced that the temperature of hot plate can not be regulated control, directly influence the quality of adhesive tape, phenomenons such as adhesive tape bubbles, a certain section adhesive tape do not vulcanizate promptly appear.
Summary of the invention:
The purpose of this utility model provides the balanced vulcanizing press hot plate temperature control device of a kind of temperature control.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of vulcanizing press hot plate temperature control device, and it comprises hot plate, hot plate is provided with 1-20 steam inlet pipe that is connected in parallel and is connected with electric control valve; Be provided with 1-20 row's condensate pipe that is connected in parallel and is connected with drain valve, row's condensation water valve, be provided with a constant voltage pressure regulator valve before electric control valve, steam enters hot plate by constant voltage pressure regulator valve, electric control valve, steam inlet pipe.
The utility model is accurate every section temperature on the control hot plate, and the steam inlet pipe on the hot plate is connected with electric control valve respectively by inlet valve; Row's condensate pipe is connected with drain valve, row's condensation water valve respectively.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, and the adjustment control of hot plate is balanced, and adjustment is convenient, fast and accurate, can guarantee the quality of production of adhesive tape.
Description of drawings:
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As seen from Figure 1, Figure 2, a kind of vulcanizing press hot plate temperature control device, it comprises hot plate 1, hot plate 1 is provided with 1-20 steam inlet pipe 3 that is connected in parallel and is connected with electric control valve 4; Be provided with 1-20 row's condensate pipe 6 that is connected in parallel and is connected with drain valve 2, row's condensation water valve 8, be provided with a constant voltage pressure regulator valve 5 before electric control valve 4, steam enters hot plate 1 by constant voltage pressure regulator valve 5, electric control valve 4, steam inlet pipe 3.
The utility model is accurate every section temperature on the control hot plate 1, and the steam inlet pipe 3 on the hot plate 1 is connected with electric control valve 4 respectively by inlet valve 7; Row's condensate pipe 6 is connected with drain valve 2, row's condensation water valve 8 respectively.
The utility model increases a constant voltage pressure regulator valve 5 before electric control valve 4, technology (being the curing temperature and the pressure of adhesive tape) requirement according to adhesive tape production, regulate the output pressure of constant voltage pressure regulator valve 5, the steam pressure that enters hot plate 1 so just can be constant, the control of the temperature of hot plate 1 has just had precondition, low phenomenon when high in the time of can not steam pressure occurring.
For further accurately controlling the temperature of hot plate 1, hot plate 1 is divided into multistage advances steam and row's condensed water (present embodiment is divided into 6 sections) respectively, inlet valve 7 is connected with electric control valve 4 respectively; Row's condensate pipe 6 is connected with drain valve 2, row's condensation water valve 8 respectively.An inlet valve 7, a row's condensation water valve 8 and a drain valve 2 promptly are installed on each section, are measured the temperature of this section hot plate 1 with thermal resistance, inlet valve 7 and row's condensation water valve 8 can be controlled it separately and open and close; When being higher than setting value, the measurement temperature of a certain section hot plate wherein (compares with setting value, setting value is for curing temperature) time just close its inlet valve 7, stop into steam, the temperature of this section hot plate what (temperature have hysteresis) of just can not rising again, having lowered slowly just then; Be lower than following its inlet valve 7 of opening of setting value in limited time when the temperature of wherein a certain section hot plate, allow steam come in, the temperature of this section hot plate will slowly rise, and just fluctuation up and down in the setting value interval of the temperature of hot plate like this realizes that really the temperature of hot plate is regulated automatically and controlled.
Its row's condensed water method is: (compare with setting value when the temperature survey of a certain section hot plate wherein is very low, setting value is for curing temperature) just open row's condensation water valve 8 of this section, drain condensed water in this section pipeline, the temperature of this section hot plate will be accelerated to rise; When the temperature survey of a certain section hot plate wherein heats up when very slow, illustrate that condensed water ponding is a lot of in this section hot plate pipeline, also can the row of opening condensation water valve 8, the interior condensed water of this section pipeline of draining is accelerated the rising of this section hot plate temperature; Condensed water is just discharged from drain valve 2 At All Other Times.
